What are the best tools for cutting the metal for installing rear fender flares?

I have air and electric cutoff wheels, regular snips and access to an air nibbler which only cuts in straight lines.

Typically I use small cutoff wheels in the die grinder... plasma cutter kicks butt, but won't leave a very clean edge and usually wants cleanup. That said - if you hit it with a plasma cutter, then grind clean with the electric angle grinder, that might be the fastest/most efficient way...

I doubt you'd have much luck cutting the arches with tinsnips, material's too thick. Likewise, I think the air nibbler would have trouble making it through all the areas with ease...

So maybe if you can borrow a plasma cutter?

Thanks, no plasma cutters available, I'll go find some of the smaller cutoff wheels for my die grinder. I have CCP Fabrication Dprod rear flares which appear to fit pretty well, some tinkering in the lower back edge will be required. Finish is excellent.

Have one flare temporarily screwed on and will be getting 3M Panel Bond for the adhesive and borrowing a gun applicator. I found that a mini grinder with a cutoff wheel works quite well, particularly for getting the welded seam off although the is some burning from the body sealants. I also used a small air die grinder, but my air compressor is not big enough to drive it well. A pair of high angle compound aviation(Weiss) snips also works quite well.

Since i am not worried about rust rather than welding all the metal back together and lots of rust preventative, I just folded together four tabs of the inner and outer panel and pop riveted them together. That made the structure stiff enough that the vibration shouldn't be much of a problem with the glue joint.

Basically I cut the seam off with the mini grinder, then used the snips to cut the outer tabs. Then between the all three tools cut the outer skin away. Then I cut the inner panel tabs , took the die grinder and sort of grooved the inner panel(remember it is badly under powered) and bent the metal back forth the break. Actually a quite clean method. Then bent and clamped the tabs with vise grips and riveted.
